# Compila o Cargo Trek (gestao de caminhao de entregas de Deseteral, Ludum Dare 54; MIT; framework ponczek do proprio
# autor, MIT; howler 2.2.3 e heapify 0.6.0, MIT) a partir do commit 027de27 de github.com/Deseteral/ludum-dare-54 e do
# commit 64a68bb de github.com/Deseteral/ponczek (o submodulo que o jogo fixa), como o README do autor: yarn 1.22.22
# nas duas pastas (yarn.lock de cada uma, "--frozen-lockfile", sem os scripts de instalacao), a lista de assets
# (scripts/generate-asset-list.ts) e "vite build", com o Node 24.21.0 de artifacts/tools.
#
# Mudanca (cargo-trek/cargo-trek-fredygames.patch): so o index.html ganha uma CSP que barra qualquer requisicao
# fora do site. O codigo do jogo nao muda.
#
#   src/FredGames.Bundler/Builds/build-cargo-trek.sh
#
# Saida: artifacts/build/cargo-trek-027de27/{cargo-trek-027de27-dist.tar.gz,licenses.txt}; o tar.gz (pasta dist/)
# sai igual em dois builds seguidos.
